The contribntion of the tumor necrosis factor (TNF) system and leptin was studied in insulin resistance and neonatal development diving the course of normal pregnancy and gestational diabetes mellittis (GDM). Thirty patients with GDM and their neonates (n = 30), 35 healthy pregnant women (15 in the first, nine in the second and 11 in the third trimester) and their neonates (n = 20), and 25 healthy matched non-pregnant women participated in the study. Significantly elevated levels Of maternal TNF-alpha, sTNF receptor (R)-1 and R-2, leptin (detected by enzyme-linked immunosorbent assay) and fasting C-peptide (measured by radioimmunossay and raised body mass index (BMI) were found in GDM patients and in the third trimester Of normal pregnancies. TNF-alpha, sTNFR-2, C-peptide, leptin concentrations and BMI positively correlated with each other in GDM. An inverse relationship between the body length, head circumference and body weight of the newborns, and maternal TNF-alpha, leptin and C-peptide concentrations was shown in GDM. In healthy pregnancies the maternal serum leptin level was in a negative linear correlation with the head circumference of the newborns. In conclusion, increased TNF-alpha and leptin levels may contribute to insulin, resistance in GDM and in the third trimester Of normal pregnancy and may negatively influence the anthroponietric parameters of the newborns.
